I bought two of these to charge an Ecoflow Pro (3.6 KwH). Really disappointing charging from these. Using in serial mode and the charging time is very slow with the Ecoflow Pro even when positioned in full sun.
I bought this panel 1 1/2 months ago to charge my River 2 Pro and Delta 2. We are wrapping up three weeks in Colorado. This panel performing great. Output on sunny days was always 200+ watts. It far exceeded my expectation. Today I was packing up the array and discovered one of the back panels was severely cracked, corner to corner. I did reposition the panels several times over the day. Towards the end of the day, one of the stands snapped back. Did that cause the damage, I don’t know. The panels were charging earlier in the day. When I put them away because rain was coming I discovered the damage. So, they were great until they weren’t. They are not the easiest panels to set up, they’re a handful. The “ hinge points” are not very flexible.
Just one outing with these so far, but the pair we purchased worked great on our first trip. They were pretty easy to set up (I'm a full-time wheelchair user) and provided plenty of power to supplement our rooftop solar in the CA desert during the late fall.
I purchased the NextGen panel recently thru an App promotion that was excellent. I already had the Original 220w Bifacial. The new one is very easy to carry and setup -- unlike the original. They both have no problem providing about 198 watts each that you can rely on.
So yesterday for the first time I hooked them both up in series on a beautiful day with very large cotton candy clouds so I did not expect much, the panels rarely received full sunlight but I wanted to know what I could expect in less than ideal conditions.
Max output was 466 watts, minimum with 100% cloud cover was 64 watts. I monitored (for awhile) the clouds and the output, when the clouds cleared output ranged between 424 to 455 watts, with some cloud cover it averaged 250 to 390 watts. I charged my Delta 2 from 48% to 100% in about 2h8m.
I am very happy with the results, now I know that in full sunlight I can expect no less then 420 watts from both panels.
Got 2 of these panels with my Delta Pro order back in January. Last power outage was during cloudy weather so decided to see what they could do. 2 panels connected in series achieved 65 watts with clouds, 455 watts once it cleared. These are my first solar panels and so far I’m impressed.
I own three of this solar panels but two of them now have a broken panel at the middle support. The material between the individual solar panels are too rigid and it makes it difficult to set up which caused the panel to crack. It’s a shame because the output prior to the solar panels cracking was impressive. I would not buy these panels again.

Thank you for choosing EcoFlow. We greatly appreciate your feedback. Your satisfaction is our top priority, and we are committed to providing you with the best possible experience
The bifacial next gen solar panels work great. I’ve seen over 200:watts produced on an 85 degree day. I just wish they had some type of handle to make it easier to carry them when they are not in the carrying case.
